Make your business
agent-payable.
The next wave of buyers won't fill in a checkout form — they'll pay over HTTP. Arispay's PayGate makes any API, storefront, or content endpoint accept x402 stablecoin payments from AI agents — USDC and EURC, settled on Base mainnet. One line of middleware.
How it works
Three steps. Zero changes to your acquirer.
Drop in PayGate
One npm install. One middleware line. Your endpoints now return HTTP 402 to unauthorized agents and 200 to paying ones.
Set your prices
Per route, per call, per byte. Charge a penny for an API hit, a dollar for a download, anything you like. We meter it.
Get paid
USDC or EURC lands straight in your wallet — final on-chain settlement in seconds, no chargebacks.
